The magic of canning
Canning is a process where the food is cooked in high heat and then placed inside a closed container to preserve the food. The closed container usually used is glass, which handles heat better than plastic. Glass also does not stain, and retain the smell of the food.
To preserve the food, the container is vacuum sealed using a vacuum sealer. Containers usually used are glass jars or mason jars.
There are two ways of doing canning:
- Water bath method is best for jams, jellies, tomatoes, vegetables and acidic foods;
- Pressure method uses a special pressure-canning equipment, and can be used for low-acid foods like vegetables and meats.
How to prepare jars for canning
The first step of the canning process is the canning itself. It starts with preparing the jars for canning:
- Use hot, soapy water to wash the jars, lids and bands;
- Rinse and drain with the mouth down;
- Use a canner or a big, deep pot to sterilize the jars;
- Fill the canner or pot with water;
- Put the jars in the rack and lower into the pot;
- Put lid on and simmer over medium heat;
- Keep the jars hot until you are ready to use them;
- In a separate sauce pan, put the lids in to sterilize;
- Put enough water to cover it;
- Bring to a simmer, but do not boil;
- Keep it hot until ready to use;
- Only the jars and lids are to be sterilized, not the bands.
How to use handheld vacuum sealer for mason jars
- Fill the washed and sterilized mason jars with food. Leave at least an inch from the mouth;
- Cover the mouth with the lid (not the band);
- Put the attachment (shaped like a top hat) onto the top of the jar. You would know if it is a good fit when you can’t see the neck of the jar;
- Connect the handheld vacuum sealer with the attachment;
- Start the vacuum seal by pressing the button to start. It will automatically stop once full vacuum seal has been achieved.
